Sales of General Motors-brand vehicles in China should reach 5 million next year, and Cadillac sales will double to 100,000, the president of General Motors said today.

Speaking at the Beijing auto show, Dan Amman said the Detroit automaker and its Chinese partners plan to open three additional factories this year and two next year. That will add production capacity of 700,000 vehicles per year.

GM hopes the "total scope" of its sales reaches 5 million units by 2015, Amman said at a news conference.

"We are moving full speed to keep up," Amman said. "We count on China for another record year in 2014."

The company plans to increase production capacity in China by 65 percent by 2020, Amman said.

General Motors is neck-and-neck with Germany's Volkswagen AG for China's biggest-selling vehicle brand.

The company said previously it, along with local partners, will invest USD 11 billion in China between this year and 2017.
